At unobserved public locations or in shunting areas, it is advisable to use shock-resistant signalling devices. Because these can take knocks and guarantee an uninterrupted useful life. WERMA offers you a wide range of signalling devices that are safe from damage thanks to their special design or a robust wire guard.
What does the IP protection category of electronic devices mean?
The IP designation, such as “IP 67”, states how well an electrical device is protected from water or foreign bodies. The two numbers mean the following:
1. Digit: contact or foreign body – protection againstSeawater is aggressive. With its high salt content, it attacks and wears down many materials. WERMA offers signalling devices that resist salt water and salty sea air: they comprise a corrosion-resistant diecast aluminium housing made of a high-quality, seawater-resistant alloy:
Signalling devices for construction sites have to withstand severe shaking and vibration. LED signalling devices are ideal here, since they
WERMA has created special stabilised LED signalling devices for use in construction. RWE, for example, uses these today as warning devices on conveyor belts or the world’s largest excavator.
